SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2″-16
ACME.

NATS Audio Link
Description
The link with the NATS IMMU implies that the audio unit can basically only be operated if connected to the
matching NATS IMMU to which the audio unit was initially fitted on the production line.
Since radio operation is impossible after the link with the NATS is disrupted theft of the audio unit is basically
useless since special equipment is required to reset the audio unit.
Initialization process for audio units that are linked to the NATS IMMU
New audio units will be delivered to the factories in the “NEW” state, i.e. ready to be linked with the vehicle's
NATS. When the audio unit in “NEW” state is first switched on at the factory, it will start up communication with
the vehicle's immobilizer control unit (IMMU) and send a code (the “audio unit Code”) to the IMMU. The IMMU
will then store this code, which is unique to each audio unit, in its (permanent) memory.
Upon receipt of the code by the IMMU, the NATS will confirm correct receipt of the audio unit code to the audio
unit. Hereafter, the audio unit will operate as normal.
During the initialization process, “NEW” is displayed on the audio unit display. Normally though, communica-
tion between audio unit and IMMU takes such a short time (300 ms) that the audio unit seems to switch on
directly without showing “NEW” on its display.
Normal operation
Each time the audio unit is switched on afterwards, the audio unit code will be verified between the audio unit
and the NATS before the audio unit becomes operational. During the code verification process, “WAIT” is
shown on the audio unit display. Again, the communication takes such a short time (300 ms) that the audio
unit seems to switch on directly without showing “WAIT” on its display.
When the radio is locked
In case of an audio unit being linked with the vehicle's NATS (immobilizer system), disconnection of the link
between the audio unit and the IMMU will cause the audio unit to switch into the lock (“SECURE”) mode in
which the audio unit is fully inoperative. Hence, repair of the audio unit is basically impossible, unless the
audio unit is reset to the “NEW” state for which special decoding equipment is required.
Clarion has provided their authorized service representatives with so called “decoder boxes” which can bring
the audio unit back to the “NEW” state, enabling the audio unit to be switched on after which repair can be car-
ried out. Subsequently, when the repaired audio unit is delivered to the final user again, it will be in the “NEW”
state to enable re-linking the audio unit to the vehicle's immobilizer system. As a result of the above, repair of
the audio unit can only be done by an authorized Clarion representative (when the owner of the vehicle
requests repair and can show personal identification).

ROUTE CALCULATION
NOTE:
Except for the ordinance-designated cities and the prefectural capitals. (Applicable areas may be changed in the updated map disc.) Symptom Possible cause Remedy
Although the system is set with
the moving direction as the prefer-
ence, it does not find the route by
matching the preference.There is no route found in that direction. This is not malfunction.
Route is not indicated.There is no road close to the destination that
can be found by this system.Reset the destination close to the road dis-
played with orange, or wider ones. Especially
with roads which have separate lanes for
opposite directions, be careful in setting the
destination or way points on it, as results may
differ depending on the lane you choose.
The starting point to the destination is too close. Set more distant destinations.
The route is not displayed continu-
ously at way points that are for
example not calculated routes
from the vehicle's current position.Suggested routes may be displayed discontinu-
ously near way points as route calculation is
done at each way point.This is not malfunction.
The suggested route the vehicle
has travelled is erased.Suggested routes are stored in memory by the
blocks; if the vehicle travels past way point 1,
the former data will be erased.This is not malfunction.
A very detoured route is sug-
gested.If there are restrictions (such as one-way traffic)
on roads close to the starting point or destina-
tion, the system may suggest a detoured route.Try slightly moving the starting point or desti-
nation.
The landmark description does
not correspond to the actual one.It may be caused by insufficient or incorrect
data on the DVD-ROM.Please wait for the update Map DVD-ROM.
The suggested route does not
exactly connect to the starting
point, way points, or destination.There is no data for route calculation closer to
these points.Set these points on the main road displayed in
thick orange. Please note that in some cases
even main roads lack the data for route calcu-
lation.
